Fanmao 4-Pack Adjustable Weld-On Shock Tabs for 3" Axle — 1/2" Hole, 1/4" Thick Heavy-Duty Steel

Heavy-duty weld-on shock tabs designed to fit 3" axle tubing, providing a secure, adjustable mounting point with a 1/2" bolt hole and 1/4" steel thickness.

These Fanmao shock tabs are engineered for fabricators and vehicle builders who need a straightforward, sturdy way to attach shock absorbers to a 3" axle tube. Made from low-carbon steel with a plain finish, each tab features a 1/2" mounting hole and 1" hole spacing for alignment flexibility. Sold as a 4-pack, they arrive ready to weld (bolts not included) and are sized and spaced for common aftermarket shocks and mounting brackets.

How do these tabs fit a 3" axle and how adjustable are they?

The tabs are contoured to weld directly onto 3" diameter axle tubing, giving a flush, strong connection when welded correctly. The internal geometry and 1" hole spacing allow small positional adjustments along the tab before final welding or when using multiple tabs for different shock placements.

• Designed to match 3" axle outer diameter for proper seating and weld clearance.
• 1" center-to-center hole spacing supports staggered mounting setups.
• 1/4" thick steel provides a balance of strength and weldability.

What materials and finishes are used, and how do they affect longevity?

Each tab is stamped from low-carbon steel and left with a plain finish, which makes them easy to weld and allows for custom coatings post-install. The plain surface may require primer or paint to protect from rust, especially in exposed off-road or marine environments.

• Low-carbon steel for reliable weldability and toughness.
• Plain finish ready for powder coat, paint, or undercoating.
• Quarter-inch thickness resists bending under typical shock loads.

Which bolt size and shock hardware work with these tabs?

The drilled mounting hole accepts a 1/2" bolt, which is a common size for many small-to-medium shocks and heim joints. Because hardware is not included, you can select stainless or grade-rated bolts and bushings to match your application and environmental needs.

• 1/2" clearance hole fits standard 1/2" bolts and sleeves.
• Choose grade 8, stainless, or zinc-plated bolts depending on strength and corrosion requirements.
• Use crush sleeves or rubber bushings to reduce wear and movement.

How many tabs come in a pack and what should I expect in the box?

This product is sold as a 4-pack of adjustable axle shock tabs, which covers typical left/right mounting pairs for front and rear installations or provides spares for multi-point setups. No bolts or weld consumables are included, so plan to have appropriate hardware and welding equipment ready.

• Package contains four (4) weld-on shock tabs.
• Bolts, nuts, and sleeves are not included—select hardware separately.
• Tabs arrive plain and ready for welding and final finishing.

Who is this for? These Fanmao weld-on shock tabs are ideal for hobbyists, custom trailer builders, off-road fabricators, and small repair shops that need an economical, robust solution for mounting shocks to 3" axles. If you weld your own brackets, want predictable hole sizing (1/2") and thickness (1/4"), and prefer to apply your own protective finish, this 4-pack gives you the raw parts to finish the job your way.
